CROSS-REFERENCE TO RELATED APPLICATIONS

The present disclosure is a continuation of International Application No. PCT/CN2023/071581 filed on Jan. 10, 2023, which claims priorities to and benefits of Chinese Patent Application No. 202210202238.7, filed on Mar. 3, 2022 and entitled “VAPORIZATION APPARATUS APPLIED TO E-CIGARETTE AND E-CIGARETTE HAVING SAME” and Chinese Patent Application No. 202210972893.0, filed on Aug. 15, 2022 and entitled “VAPORIZATION APPARATUS APPLIED TO E-CIGARETTE AND E-CIGARETTE HAVING SAME”. The entire content of the above-referenced applications is incorporated herein by reference.

FIELD

The present disclosure relates to the field of e-cigarette technologies, and specifically, to a vaporization apparatus applied to an e-cigarette and an e-cigarette having the same.

BACKGROUND

As a substitute of conventional tobacco, a demand for e-cigarettes is increased year by year. The e-cigarette can not only simulate a sensory experience of smoking, but also cause far less damage to health than the conventional tobacco.

The e-cigarette usually includes a cartridge and a cigarette rod. The cartridge is mounted on the cigarette rod and can produce smoke to be inhaled by a human body. The cartridge is provided with a liquid storage bin, an air passage, a vaporization bin, and a vaporization core. E-liquid for generating vapor is provided inside the liquid storage bin. The e-liquid enters the vaporization bin through the vaporization core and is vaporized to form vapor. The vapor is inhaled by a user through the air passage.

When a user inhales an e-cigarette in the related art, liquid e-liquid is easily inhaled, affecting user experience. An airflow channel in an upper cover of a vaporization apparatus used as a cartridge is excessively narrow in a width direction, so that a vaporization core of the vaporization apparatus may increase resistance to inhalation during operation. As a result, a flow rate of vapor in a vaporization bin of the vaporization apparatus is relatively high, and liquid e-liquid may be formed through condensation when the vapor with a relatively high flow rate collides with an inner wall of the vaporization apparatus.

The vaporization core 3 is arranged in the shell 1 and is in communication with the liquid storage bin 11 and the vaporization bin 13, and the vaporization core 3 is configured to vaporize a to-be-vaporized medium in the liquid storage bin 11.

For example, in examples of FIG. 1 to FIG. 3 , the air passage 12 and the liquid storage bin 11 may be arranged along a width direction of the shell 1 (for example, a left-right direction in FIG. 1 ), and the liquid storage bin 11 is configured to hold a liquid to-be-vaporized medium such as e-liquid.

Therefore, designs of the cross-sectional areas of the vaporization bin exit 2, the air passage 12, the inhalation channel 145, and the inhalation inlet 141 may be relatively proper.

For example, when a ratio of an absolute value of a difference between the cross-sectional area of the air passage 12 and the cross-sectional area of the inhalation inlet 141 to the cross-sectional area of the air passage 12 is less than or equal to 20%, it indicates that the cross-sectional area of the air passage 12 is basically equal to the cross-sectional area of the inhalation inlet 141, and a vaporized medium can flow smoothly in the air passage 12. Therefore, during operation of the vaporization apparatus 100, it may be ensured that air and vapor formed through vaporization in the vaporization bin 13 are fully mixed and flow to the air passage 12 smoothly to reach the inhalation inlet 141, thereby reducing resistance during inhalation by a user, preventing a mixed airflow from forming condensate in the air passage 12, preventing liquid e-liquid from being inhaled during inhalation by the user, and improving user experience.

The following describes an operation process when the vaporization apparatus 100 is applied to an e-cigarette by using an example.

After the vaporization apparatus 100 is combined with a cigarette rod, the user inhales at the inhalation inlet 141. In this case, a pneumatic sensor (such as a microphone) in the cigarette rod senses the inhalation, to cause a power supply in the cigarette rod to be electrically connected to the vaporization core 3, the vaporization core 3 operates, for example, the vaporization core 3 performs heating, and the to-be-vaporized medium such as e-liquid in the liquid storage bin 11 moves toward the vaporization bin 13 and is heated by the vaporization core 3 to form vapor (including but not limited to aerosols, suspended liquids, low-temperature vapors, and volatile gases) in the vaporization bin 13. In addition, external air enters the vaporization bin 13 through the air inlet 71 and is mixed with the vapor in the vaporization bin 13, and mixed vapor is inhaled by the user through the inhalation inlet 141 through the vaporization bin exit 2, the air passage 12, and the inhalation channel 145, to meet a use requirement of the user. When the user stops inhalation from the inhalation inlet 141, the to-be-vaporized such as e-liquid in the liquid storage bin 11 stops entering the vaporization bin 13 from the vaporization core 3, thereby preventing ineffective consumption of the to-be-vaporized medium in the liquid storage bin 11, and improving utilization of the to-be-vaporized medium. It should be noted herein that, in some e-cigarettes, the vaporization apparatus 100 and the cigarette rod are set to separated structures and may be detachably combined, and in some e-cigarettes, the vaporization apparatus 100 and the cigarette rod are set to an undetachable structure, which is not specifically limited herein.

According to the vaporization apparatus 100 applied to an e-cigarette provided in this embodiment of the present disclosure, the ratio of the absolute value of the difference between the cross-sectional areas of at least two of the vaporization bin exit 2, the air passage 12, the inhalation channel 145, and the inhalation inlet 141 to the cross-sectional area of any one of the vaporization bin exit 2, the air passage 12, the inhalation channel 145, and the inhalation inlet 141 is less than or equal to 20%, so that a mixed airflow in the vaporization bin 13 can flow to the air passage 12 smoothly, thereby reducing resistance during inhalation by the user, preventing the mixed airflow from forming condensate in the air passage 12, and improving user experience.

According to some embodiments of the present disclosure, the ratio of the absolute value of the difference between the cross-sectional areas of any two of the vaporization bin exit 2, the air passage 12, the inhalation channel 145, and the inhalation inlet 141 to the cross-sectional area of any one of the air passage 12 and the inhalation inlet 141 is less than or equal to 20%. A first case may be that a ratio of an absolute value of a difference between the cross-sectional areas of the vaporization bin exit 2 and the air passage 12 to the cross-sectional area of any one of the air passage 12 and the inhalation inlet 141 is less than or equal to 20%. A second case may be that a ratio of an absolute value of a difference between the cross-sectional areas of the vaporization bin exit 2 and the inhalation channel 145 to the cross-sectional area of any one of the air passage 12 and the inhalation inlet 141 is less than or equal to 20%. A third case may be that a ratio of an absolute value of a difference between the cross-sectional areas of the vaporization bin exit 2 and the inhalation inlet 141 to the cross-sectional area of any one of the air passage 12 and the inhalation inlet 141 is less than or equal to 20%. A fourth case may be that a ratio of an absolute value of a difference between the cross-sectional areas of the air passage 12 and the inhalation channel 145 to the cross-sectional area of any one of the air passage 12 and the inhalation inlet 141 is less than or equal to 20%. A fifth case may be that a ratio of an absolute value of a difference between the cross-sectional areas of the air passage 12 and the inhalation inlet 141 to the cross-sectional area of any one of the air passage 12 and the inhalation inlet 141 is less than or equal to 20%. A sixth case may be that a ratio of an absolute value of a difference between the cross-sectional areas of the inhalation channel 145 and the inhalation inlet 141 to the cross-sectional area of any one of the air passage 12 and the inhalation inlet 141 is less than or equal to 20%. Therefore, the mixed airflow in the vaporization bin 13 can smoothly flow to the mouth of the user through the air passage 12 and the inhalation channel 145, thereby reducing resistance during inhalation by the user.

According to some embodiments of the present disclosure, the cross-sectional area of the vaporization bin exit 2 is S₁, the cross-sectional area of the air passage 12 is S₂, the cross-sectional area of the inhalation channel 145 is S₃, the cross-sectional area of the inhalation inlet 141 is S₄, and S₁, S₂, S₃, and S₄ respectively meet the following conditions: S₁ is approximately greater than or equal to 3 mm² and approximately less than or equal to 6 mm², S₂ is approximately greater than or equal to 3 mm² and approximately less than or equal to 6 mm², S₃ is approximately greater than or equal to 3 mm² and approximately less than or equal to 6 mm², and S₄ is approximately greater than or equal to 3 mm² and approximately less than or equal to 6 mm². When S₁ is less than 3 mm², the cross-sectional area of the vaporization bin exit 2 is relatively small, the mixed airflow in the vaporization bin 13 can hardly flow to the air passage 12, which increases resistance during inhalation by the user and affects user experience; and when S₁ is greater than 6 mm², the cross-sectional area of the vaporization bin exit 2 is relatively great, a vaporized medium in the vaporization bin 13 flows to the air passage 12 before fully mixed with the air, which also affects user experience. When S₂ is less than 3 mm², the cross-sectional area of the air passage 12 is relatively small, in this case, the air passage 12 is relatively narrow, and an amount of vapor that can be inhaled by the user during inhalation is relatively small; and when Sz is greater than 6 mm², the cross-sectional area of the air passage 12 is relatively large, which increases resistance during inhalation by the user.

When S₃ is less than 3 mm², the cross-sectional area of the inhalation channel 145 is relatively small, and the mixed airflow in the air passage 12 can hardly flow to the inhalation channel 145, which increases resistance during inhalation by the user and affects user experience; and when S₃ is greater than 6 mm², the cross-sectional area of the inhalation channel 145 is relatively large, and the user may inhale a large amount of vapor during inhalation, which also affects user experience. When S₄ is less than 3 mm², the cross-sectional area of the inhalation inlet 141 is relatively small, an amount of vapor that can be inhaled by the user during inhalation is relatively small, and when an inhalation force of the user is relatively large, the user may be choked by the vapor; and when S₄ is greater than 6 mm², the cross-sectional area of the inhalation inlet 141 is relatively great, which increases resistance during inhalation by the user.

The cross-sectional areas of the vaporization bin exit 2, the air passage 12, the inhalation channel 145, and the inhalation inlet 141 may be equal to each other. Therefore, when the user inhales, the mixed airflow in the vaporization bin 13 can smoothly flow to the mouth of the user.

Therefore, by making S₁, S₂, S₃, and S₄ to respectively meet the following conditions: 3 mm²≤S₁≤6 mm², 3 mm²≤S₂≤6 mm², 3 mm²≤S 3≤6 mm², and 3 mm²≤S_(4≤6) mm², designs of the cross-sectional areas of the vaporization bin exit 2, the air passage 12, the inhalation channel 145, and the inhalation inlet 141 may be relatively proper, and resistance during inhalation by the user may be reduced while ensuring that the vaporized medium can be fully mixed with the air. The mixed airflow in the vaporization bin 13 can quickly and smoothly flow to the mouth of the user through the inhalation inlet 141, and the user can inhale a proper amount of vapor during inhalation, thereby improving user experience.

According to some embodiments of the present disclosure, the shell 1 includes a length direction (for example, the up-down direction in FIG. 1 ), a width direction (for example, the left-right direction in FIG. 1 ), and a thickness direction (for example, a left-right direction in FIG. 2 ). A maximum size of the shell 1 in the length direction is greater than maximum sizes of the shell 1 in the width direction and the thickness direction, and the air passage 12 deviates from a central axis of the inhalation inlet 141 along the width direction. That is, a central axis of the air passage 12 deviates from the central axis of the inhalation inlet 141 along the width direction. Referring to FIG. 1 , along the length direction of the shell 1, the central axis of the inhalation inlet 141 basically overlaps with a central axis of the shell 1. In other words, the inhalation inlet 141 is located in a middle portion of an end of the shell 1. The central axis of the air passage 12 may be located on a left side or a right side of the central axis of the shell 1. Therefore, when the user inhales through the inhalation inlet 141, the vapor in the vaporization bin 13 may flow to a middle portion of the mouth of the user more smoothly through the air passage 12 and the inhalation channel 145, and the vapor may be uniformly distributed in the mouth of the user, thereby further improving user experience.

According to a further embodiment of the present disclosure, referring to FIG. 1 and FIG. 3 , the vaporization apparatus 100 applied to an e-cigarette further includes a vaporization core fixing structure 4 and an elastic seal member 5. A vaporization core mounting cavity 41 and a vent cavity 42 that are spaced from each other are formed in the vaporization core fixing structure 4, the vent cavity 42 is in communication with the vaporization bin 13, and the vaporization core 3 is arranged in the vaporization core mounting cavity 41. The elastic seal member 5 is sleeved on the vaporization core fixing structure 4, at least a part of the elastic seal member 5 is located between an inner wall surface of the shell 1 and the vaporization core fixing structure 4, the elastic seal member 5 and the vaporization core fixing structure 4 define a vent channel 6, and the vent channel 6 is in communication with the vent cavity 42 and the liquid storage bin 11.

For example, in the examples of FIG. 1 and FIG. 3 , the vaporization core mounting cavity 41 and the vent cavity 42 may be spaced from each other along the width direction of the shell 1, and a shape of the vaporization core mounting cavity 41 matches a shape of the vaporization core 3, so that the vaporization core 3 is firmly mounted in the vaporization core fixing structure 4. The vaporization core fixing structure 4 may be sealedly connected to the inner wall surface of the shell 1 through the elastic seal member 5, so that the to-be-vaporized medium in the liquid storage bin 11 may be prevented from flowing from a gap between the vaporization core fixing structure 4 and the inner wall surface of the shell 1 to the vaporization bin 13, and waste of the to-be-vaporized may be further prevented.

During operation of the vaporization apparatus 100, when the to-be-vaporized medium in the liquid storage bin 11 moves to the vaporization bin 13 through the vaporization core 3, the liquid storage bin 11 is in a negative pressure state. In this case, a pressure of the liquid storage bin 11 is less than a pressure of the vaporization bin 13, the air in the vaporization bin 13 flows to the vent cavity 42 and flows to the liquid storage bin 11 through the vent channel 6, so that the pressure of the liquid storage bin 11 and the pressure of the vaporization bin 13 is balanced. Therefore, the to-be-vaporized medium in the liquid storage bin 11 can continuously move to the vaporization bin 13 through the vaporization core 3, and the vaporization core 3 can obtain sufficient to-be-vaporized mediums to maintain a vapor generation effect.

Further, referring to FIG. 9 to FIG. 12 , at least one vent hole 43 and at least one vent groove 44 are formed in an outer peripheral surface of the vaporization core fixing structure 4, the vent hole 43 runs through an outer peripheral wall of the vaporization core fixing structure 4 and is in communication with the inside of the vent cavity 42, an end of the vent groove 44 is connected to the vent hole 43, an other end of the vent groove 44 runs through a side surface of the vaporization core fixing structure 4 that faces the liquid storage bin 11, and the vent hole 43, the vent groove 44, and the elastic seal member 5 jointly define the vent channel 6. When the pressure of the vaporization bin 13 is greater than the pressure of the liquid storage bin 11, the airflow in the vaporization bin 13 may flow to the vent cavity 42, the airflow in the vent cavity 42 may flow to the vent groove 44 through the vent hole 43, and the airflow flows from an end of the vent groove 44 to the other end, so that the airflow in the vaporization bin 13 flows to the liquid storage bin 11, to achieve an objective of adjusting a pressure difference between the liquid storage bin 11 and the vaporization bin 13.

Furthermore, a length of the vent groove 44 is greater than a distance between the vent hole 43 and the other end of the vent groove 44. As shown in FIG. 9 to FIG. 12 , the vent hole 43 is formed at a side of the vaporization core fixing structure 4 along the thickness direction of the shell 1, a part of the vent groove 44 extends to an other side of the vaporization core fixing structure 4 along the thickness direction of the shell 1, and the other end of the vent groove 44 is located at an end of the vaporization core fixing structure 4 along the width direction of the shell 1. In this case, the vent groove 44 is in a shape of a broken line, and the length of the vent groove 44 is increased. Therefore, when the vent channel 6 is open, the vent groove 44 may store a few to-be-vaporized media, so that the to-be-vaporized is prevented from directly flowing to the vaporization bin 13, thereby preventing the user from inhaling the to-be-vaporized medium and ensuring user experience.

Further, the vent groove 44 includes a first vent groove section 441 and a second vent groove section 442, an end of the first vent groove section 441 is connected to the vent hole 43, and an other end of the first vent groove section 441 extends to the other side of the vaporization core fixing structure 4 along the thickness direction of the shell 1. Referring to FIG. 10 , the first vent groove section 441 is L-shaped, and the first vent groove section 441 may include a first vent sub-section and a second vent sub-section. The first vent sub-section extends along a thickness direction of the vaporization core fixing structure 4, an end of the first vent sub-section is connected to the vent hole 43, an end of the second vent sub-section is connected to an other end of the first vent sub-section, and the second vent sub-section extends along a circumferential direction of the vaporization core fixing structure 4 to an other side of the vaporization core fixing structure 4 along a width direction. Therefore, a length of the first vent groove section 441 is increased, and the first vent groove section 441 has a simple structure and is easy to process.

An end of the second vent groove section 442 is connected to the other end of the first vent groove section 441, and an other end of the second vent groove section 442 runs through the side surface of the vaporization core fixing structure 4 that faces the liquid storage bin 11. Referring to FIG. 10 , the second vent groove section 442 is U-shaped, and the second vent groove section 442 may include a third vent sub-section, a fourth vent sub-section, and a fifth vent sub-section. The third vent sub-section extends along the thickness direction of the vaporization core fixing structure 4, and an end of the third vent sub-section is connected to the other end of the first vent groove section 441. An end of the fourth vent sub-section is connected to an other end of the third vent sub-section, and an other end of the fourth vent sub-section extends along the circumferential direction of the vaporization core fixing structure 4 to an end of the vaporization core fixing structure 4 along a length direction. The fifth vent sub-section extends along the thickness direction of the vaporization core fixing structure 4, an end of the fifth vent sub-section is connected to the other end of the fourth vent sub-section, and an other end of the fifth vent sub-section runs through an other side surface of the vaporization core fixing structure 4 along the thickness direction. Therefore, a length of the second vent groove section 442 is increased, and the length of the vent groove 44 may be effectively increased, so that the length of the vent groove 44 is greater than the distance between the vent hole 43 and the other end of the vent groove 44. In addition, the second vent groove section 442 has a simple structure and is easy to process.

According to some other embodiments of the present disclosure, as shown in FIG. 13, the vent hole 43 is formed at an end of the vaporization core fixing structure 4 along the width direction of the shell 1, and the other end of the vent groove 44 is located at a side of the vaporization core fixing structure 4 along the thickness direction of the shell 1. With such arrangement, the length of the vent groove 44 is relatively short, and when the pressure of the vaporization bin 13 is greater than the pressure of the liquid storage bin 11, the airflow in the vent groove 44 can quickly open the vent channel 6, so that the pressure of the liquid storage bin 11 and the pressure of the vaporization bin 13 may be quickly adjusted.

As shown in FIG. 13 , the vent groove 44 includes a third vent groove section 443 and a fourth vent groove section 444. The third vent groove section 443 extends along the circumferential direction of the vaporization core fixing structure 4, an end of the third vent groove section 443 is connected to the vent hole 43, and an other end of the third vent groove section 443 extends to a side of shell 1 along the thickness direction. An end of the fourth vent groove section 444 is connected to the other end of the third vent groove section 443, and an other end of the fourth vent groove section 444 extends along the length direction of the shell 1 and runs through the side surface of the vaporization core fixing structure 4 that faces the liquid storage bin 11. In this case, the vent groove 44 is L-shaped. Therefore, the vent groove 44 has a simple structure and is easy to process.

According to some embodiments of the present disclosure, a connection position of the vent groove 44 and the vent hole 43 is away from the liquid storage bin 11 relative to the vent hole 43. With such arrangement, when the e-liquid in the liquid storage bin 11 flows into the vent groove 44 and enters the vaporization bin 13 through the vent hole 43, the vent hole 43 is located at a relatively high position and is closer to the liquid storage bin 11, so that entering of the e-liquid from the vent groove 44 to the vent hole 43 is from a “low position” to a “high position”, thereby preventing the to-be-vaporized medium in the liquid storage bin 11 from flowing into the vaporization bin 13 through the vent groove 44 and the vent hole 43, and preventing the user from inhaling the to-be-vaporized medium during inhalation.

According to some embodiments of the present disclosure, the elastic seal member 5 includes an end seal portion 51, a first seal portion 52, and a second seal portion 53, where the end seal portion 51 covers at least an edge part of the side surface of the vaporization core fixing structure 4 that faces the liquid storage bin 11. Both the first seal portion 52 and the second seal portion 53 are connected to the end seal portion 51 and located on an outer peripheral side of the vaporization core fixing structure 4, the vent channel 6 is provided between the first seal portion 52 and the vaporization core fixing structure 4, and a maximum size of the second seal portion 53 in the length direction of the shell 1 is less than a maximum size of the first seal portion 52 in the length direction of the shell 1. With reference to FIG. 1 and FIG. 3 , the end seal portion 51 may be connected to an end of the vaporization core fixing structure 4 that is close to the liquid storage bin 11, to firmly mount the elastic seal member 5 on the vaporization core fixing structure 4. In addition, both the first seal portion 52 and the second seal portion 53 may be sleeved on the outer peripheral side of the vaporization core fixing structure 4, and the vaporization core fixing structure 4 may be sealedly connected to the inner wall surface of the shell 1 through the first seal portion 52 and the second seal portion 53, so that the to-be-vaporized medium in the liquid storage bin 11 may be prevented from flowing to the vaporization bin 13 from the gap between the vaporization core fixing structure 4 and the inner wall surface of the shell 1.

Further, referring to FIG. 1 , the first seal portion 52 covers the vent hole 43 and the vent groove 44. When the pressure of the liquid storage bin 11 is greater than or equal to the pressure of the vaporization bin 13, the first seal portion 52 blocks the vent hole 43 and the vent groove 44 and forms the vent channel 6, to prevent waste of the to-be-vaporized medium caused by flowing of the to-be-vaporized medium in the liquid storage bin 11 to the vaporization bin 13. When the pressure of the liquid storage bin 11 is less than the pressure of the vaporization bin 13, the first seal portion 52 is deformed. In this case, the vent channel 6 is open, to balance the pressure of the liquid storage bin 11 and the pressure of the vaporization bin 13.

Further, a first seal rib 521 extending along the circumferential direction of the vaporization core fixing structure 4 is arranged on an outer peripheral surface of the first seal portion 52, and at least one second seal rib 531 extending along the circumferential direction of the vaporization core fixing structure 4 is arranged on an outer peripheral surface of the second seal portion 53, where the second seal rib 531 is connected to the first seal rib 521. For example, in examples of FIG. 14 to FIG. 17 , there is one second seal rib 531, the first seal rib 521 is located at an edge of an end of the first seal portion 52 that is away from the inhalation inlet 141, and the second seal rib 531 is located at an edge of an end of the second seal portion 53 that is away from the inhalation inlet 141. By arranging the first seal rib 521 and the second seal rib 531, the first seal portion 52 and the second seal portion 53 are in interference fit with the inner wall surface of the shell 1, so that sealing performance between the vaporization core fixing structure 4 and the inner wall surface of the shell 1 may be improved, and the to-be-vaporized medium in the liquid storage bin 11 may be further prevented from leaking to the vaporization bin 13.

According to some embodiments of the present disclosure, a boss 45 is arranged on the outer peripheral surface of the vaporization core fixing structure 4, the boss 45 includes a first boss 451 and a second boss 452 that are connected to each other, and a height of the first boss 451 is greater than a height of the second boss 452. Referring to FIG. 9 to FIG. 13 , the first boss 451 encloses an outer peripheral side of the vaporization core mounting cavity 41, the second boss 452 encloses an outer peripheral side of the vent cavity 42, and a distance between the first boss 451 and a side surface of the vaporization core fixing structure 4 that is close to the liquid storage bin 11 along the thickness direction is less than a distance between the second boss 452 and the side surface of the vaporization core fixing structure 4 that is close to the liquid storage bin 11 along the thickness direction. During mounting, a free end of the first seal portion 52 abuts against the second boss 452, and a free end of the second seal portion 53 abuts against the first boss 451. Therefore, the elastic seal portion may be prevented from being reversely mounted, and the assembly efficiency of the vaporization apparatus 100 may be improved.

According to some embodiments of the present disclosure, as shown in FIG. 14 to FIG. 17 , the end seal portion 51 includes at least one vent elastic portion 511, and the at least one vent elastic portion 511 covers an end of the vent channel 6 that faces the liquid storage bin 11. When the pressure of the vaporization bin 13 is greater than the pressure of the liquid storage bin 11, the vent elastic portion 511 is deformed under the action of a pressure difference to open the vent channel 6, and when the pressure of the vaporization bin 13 is not greater than the pressure of the liquid storage bin 11, the vent elastic portion 511 blocks the vent channel 6. The vent elastic portion 511 closes the vent channel 6 under the action of the elastic resilience of the vent elastic portion, to cause the vent elastic portion 511 to block the vent channel 6.

It should be noted that, a specific force is required to push the vent elastic portion 511 to generate elastic deformation, so that the vent channel 6 can be open only when a difference between the pressure of the vaporization bin 13 and the pressure of the liquid storage bin 11 can push the vent elastic portion 511 to generate elastic deformation. That is, by setting a material and a structure of the vent elastic portion 511, the vent elastic portion 511 may be pushed to open the vent channel 6 when the pressure of the vaporization bin 13 is greater than the pressure of the liquid storage bin 11, or the vent elastic portion 511 is pushed to open the vent channel 6 only when a difference between the pressure of the vaporization bin 13 and the pressure of the liquid storage bin 11 reaches a specific value.

According to some embodiments of the present disclosure, the vaporization apparatus 100 applied to an e-cigarette further includes a baffle 46, and the baffle 46 is arranged at a position where the air passage 12 is in communication with the vaporization bin 13. Referring to FIG. 10 to FIG. 12 , the baffle 46 is arranged at a side of the vaporization core fixing structure 4 that is close to the air passage 12, the baffle 46 is also located at a side of the vaporization core fixing structure 4 that is close to the vaporization bin 13 along the thickness direction, and a free end of the baffle 46 extend along a direction toward the vaporization bin 13. Therefore, the baffle 46 may block an airflow flowing from the vaporization bin 13 to the air passage 12, so that a flow rate of the airflow is reduced, the vaporized medium in the airflow is fully mixed with the air, and experience during inhalation by the user is ensured.

As shown in FIG. 4 and FIG. 5 , the shell 1 includes a housing 14 and a base assembly 7. An opening 142 is provided at an end of the housing 14 along a length direction, the inhalation inlet 141 is provided at an other end of the housing 14 along the length direction, the base assembly 7 covers the opening 142, the air inlet 71 is formed in the base assembly 7, and the vaporization bin 13 is jointly defined by the housing 14, the vaporization core 3, and the base assembly 7. With such arrangement, the air inlet 71 is provided close to the vaporization bin 13, so that during operation of the vaporization apparatus 100, external air can quickly enter the vaporization bin 13 and be mixed with the vaporized medium, and the mixed airflow in the vaporization bin 13 can quickly flow to the air passage 12.

In some embodiments, the free end of the baffle 46 extends out of an end surface of a side wall of the air passage 12. Referring to FIG. 1 , that is, a minimum distance between an end of the baffle 46 that is close to the base assembly 7 and the base assembly 7 is less than a minimum distance between an end of the air passage 12 that is close to the base assembly 7 and the base assembly 7. In this way, when the airflow in the vaporization bin 13 flows to the air passage 12, the baffle 46 can block the airflow, to reduce a flow rate of the airflow, so that the vaporized medium and the air can be fully mixed in the vaporization bin 13.

According to some embodiments of the present disclosure, the vaporization apparatus 100 applied to an e-cigarette further includes a vaporization core seal member 9, and the vaporization core seal member 9 is sleeved on an edge of the vaporization core 3 to form sealing.

According to some embodiments of the present disclosure, the vaporization core 3 includes a porous body and a heating body, the porous body includes a liquid absorbing surface and a vaporization surface, the heating body is arranged on the vaporization surface, the vaporization core seal member 9 includes a seal edge covering an edge of the vaporization surface and a seal portion located between an outer peripheral wall of the porous body and an inner wall of the housing 1, and the seal portion extends along a direction toward the vaporization bin 13 to form the baffle 46.

According to some embodiments of the present disclosure, a separating rib 15 is constructed on the inner wall surface of the shell 1, and the separating rib 15 separates the liquid storage bin 11 and the air passage 12. As shown in FIG. 4 and FIG. 5 , an end of the separating rib 15 is connected to an end of the shell 1 along the length direction, an other end of the separating rib 15 extends toward the base assembly 7 along the length direction of the shell 1, and the liquid storage bin 11 and the air passage 12 are respectively located at two sides of the separating rib 15, so that the liquid storage bin 11 is spaced from the air passage 12. Therefore, the to-be-vaporized medium in the liquid storage bin 11 may be prevented from flowing to the air passage 12, and the mixed airflow in the air passage 12 may be also prevented from flowing to the liquid storage bin 11, thereby ensuring normal operation of the vaporization apparatus 100.

The liquid storage bin 11, the vaporization core 3, the vaporization core fixing structure 4, and the elastic seal member 5 are located at a side of the separating rib 15 in the length direction of the shell 1, and the air passage 12 is located at an other side of the separating rib 15 in the width direction of the shell 1. For example, in the example of FIG. 1 , the liquid storage bin 11, the vaporization core 3, and the vaporization core fixing structure 4 are arranged along the length direction of the shell 1, the vaporization core 3 is located at an end of the liquid storage bin 11 that is close to the vaporization bin 13, and the air passage 12 and the liquid storage bin 11 are arranged along the width direction of the shell 1, thereby ensuring the structure compactness of the vaporization apparatus 100. The baffle 46 may be arranged at an end (not shown in the figure) of the separating rib 15 that is close to the base assembly 7. Specifically, the baffle 46 may be a structural member integrally formed with the separating rib 15. For example, a free end of the separating rib 15 may extend toward the base assembly 7, the free end of the separating rib 15 extends out of a lower end surface of the vaporization core fixing structure 4, and the free end of the baffle 46 extends along a direction toward the base assembly 7, to block the airflow flowing to the air passage 12.

The free end of the baffle 46 extends out of the lower end surface of the vaporization core fixing structure 4. In other words, the minimum distance between the end of the baffle 46 that is close to the base assembly 7 and the base assembly 7 is less than a minimum distance between an end of the vaporization core fixing structure 4 that is close to the base assembly 7 and the base assembly 7. In this way, the airflow flowing to the air passage 12 is blocked, and a flow rate of the airflow is reduced, thereby ensuring that the vaporized medium and the air can be fully mixed.

According to some embodiments of the present disclosure, referring to FIG. 18 to FIG. 23 , the base assembly 7 includes a base 72, a conductive nail 73, and a first air guide metal plate 74. The base 72 includes a base bottom wall 721 and a support structure 722 extending from the base bottom wall 721 toward the vaporization bin 13, and the conductive nail 73 runs through the base bottom wall 721 and is electrically connected to the vaporization core 3, to heat the vaporization core 3, so as to vaporize the to-be-vaporized medium flowing through the vaporization core 3. The air inlet 71 is formed in the base bottom wall 721, the first air guide metal plate 74 is supported on the support structure 722 and covers the air inlet 71, multiple diverting holes 741 and a first avoiding hole 742 are provided in the first air guide metal plate 74, the multiple diverting holes 741 correspond to the air inlet 71, and the conductive nail 73 runs through the first avoiding hole 742 to be electrically connected to the vaporization core 3. The vaporization core 3 includes a porous body and a heating body arranged on the porous body, and the conductive nail 73 runs through the first avoiding hole 742 to be electrically connected to the heating body. The first air guide metal plate 74 can divert air entering from the air inlet 71, so that the air in the vaporization bin 13 is uniformly distributed, thereby ensuring that the vaporized to-be-vaporized medium and the air are uniformly mixed in the vaporization bin 13.

The porous body includes a liquid absorbing surface and a vaporization surface that are arranged opposite to each other, the heating body is arranged on the vaporization surface, a space between the vaporization surface and the base 72 forms the vaporization bin 13, and the porous body may be a porous ceramic substrate. The to-be-vaporized medium may enter the vaporization surface from the liquid absorbing surface, form a vaporized medium under a heating action of the heating body, and be outputted to the vaporization bin 13 from the vaporization surface.

The base assembly 7 further includes a liquid absorbing body 8, the liquid absorbing body 8 is supported on the support structure 722, a first through hole and a second through hole are provided on the liquid absorbing body 8, the conductive nail 73 runs through the first through hole to be electrically connected to the heating body, and a position of the second through hole corresponds to a position of the air inlet 71. After the to-be-vaporized medium is vaporized in the vaporization bin 13, if the vaporization core 3 stops operating, the to-be-vaporized medium may be condensed again, and the liquid absorbing body can absorb the condensed to-be-vaporized medium. In this way, the condensed to-be-vaporized medium can be prevented from leaking from the air inlet 71, thereby improving cleanness during use of the vaporization apparatus 100, and also preventing a structure (for example, a cigarette rod of an e-cigarette) connected to the vaporization apparatus 100 from being corroded and blocked by the condensed to-be-vaporized medium.

According to some embodiments of the present disclosure, as shown in FIG. 2 , an end surface of the free end of the baffle 46 is spaced from the first air guide metal plate 74 along the length direction to define the vaporization bin exit 2, and the vaporization bin exit 2 is jointly defined by the inner wall surface of the shell 1, the end surface of the free end of the baffle 46, and the first air guide metal plate 74. In this case, a cross section of the vaporization bin exit 2 is approximately in a shape of U or a rectangle. During operation of the vaporization apparatus 100, the mixed airflow in the vaporization bin 13 may flow to the air passage 12 through the vaporization bin exit 2, and then flow to the mouth of the user through the inhalation inlet 141 in communication with the air passage 12. Therefore, the baffle 46 has a simple structure and is easy to process.

According to some other embodiments of the present disclosure, the end surface of the free end of the baffle 46 is in contact with a side surface of the first air guide metal plate 74 that faces the vaporization core 3; and at least one side of the baffle 46 in the thickness direction of the shell 1 is spaced from a corresponding side wall in the thickness direction of the shell 1 to define the vaporization bin exit 2, and the vaporization bin exit 2 is jointly defined by the inner wall surface of the shell 1, a side surface of the at least one side of the baffle 46 in the thickness direction of the shell 1, and the first air guide metal plate 74. For example, two ends of the baffle 46 in the thickness direction of the shell 1 are spaced from the corresponding side wall in the thickness direction of the shell 1. In this case, there are two vaporization bin exits 2, and the two vaporization bin exits 2 are respectively located at two sides of the baffle 46 in the thickness direction of the shell 1. Alternatively, an end of the baffle 46 in the thickness direction of the shell 1 is spaced from the corresponding side wall in the thickness direction of the shell 1. In this case, there is one vaporization bin exit 2, and the vaporization bin exit 2 is located at a side of the baffle 46 in the thickness direction of the shell 1. During operation of the vaporization apparatus 100, the mixed airflow in the vaporization bin 13 may flow to the air passage 12 through the vaporization bin exit 2, and then flow to the mouth of the user through the inhalation inlet 141 in communication with the air passage 12. Therefore, the baffle 46 has a simple structure and is easy to process.

According to still some other embodiments of the present disclosure, the base assembly 7 includes a second air guide metal plate 75. The second air guide metal plate 75 is arranged at a side of the liquid absorbing body 8 that is away from the base 72. A second avoiding hole 752 and a third through hole 751 are provided in the second air guide metal plate 75. The conductive nail 73 runs through the second avoiding hole 752 to be electrically connected to the heating body. The third through hole 751 corresponds to an air outlet end of the air inlet 71, and an air-permeable and e-liquid-resistant member 10 is arranged at the third through hole 751. Referring to FIG. 23 , FIG. 25 , FIG. 26 , and FIG. 27 , in the width direction of the shell 1, a length of the liquid absorbing body 8 is approximately equal to a width of the shell 1, so that the liquid absorbing body 8 can face the liquid storage bin 11 and the vaporization bin 13, and a liquid absorbing area of the liquid absorbing body 8 is increased. Therefore, the liquid absorbing body 8 can better absorb the condensed to-be-vaporized medium, thereby preventing the condensed to-be-vaporized medium from leaking from the air inlet 71 and improving cleanness during use of the vaporization apparatus 100. The liquid absorbing body 8 has a soft texture. Therefore, by arranging the second air guide metal plate 75 on the liquid absorbing body 8, a structural strength of the liquid absorbing body 8 may be improved, and the liquid absorbing body 8 may be prevented from generating deformation. Optionally, a double-sided adhesive 101 is bonded to a side of the air-permeable and e-liquid-resistant member 10 that is away from the liquid storage bin 11, and the air-permeable and e-liquid-resistant member 10 may be bonded to the second air guide metal plate 75 and the support structure 722 through the double-sided adhesive 101. The air-permeable and e-liquid-resistant member 10 may ensure that the air in the air inlet 71 flows into the vaporization bin 13, and may also prevent the condensed to-be-vaporized medium in the vaporization bin 13 from flowing to the air inlet 71.

According to some embodiments of the present disclosure, referring to FIG. 1 and FIG. 3 , the housing 14 includes a body 143 and an inhalation shell 144. The liquid storage bin 11, the air passage 12, and the vaporization bin 13 are arranged in the body 143, and the body 143 is provided with the air inlet 71. The inhalation shell 144 is arranged on the body 143, the inhalation inlet 141 is formed in the inhalation shell 144, and the inhalation shell 144 and the body 143 jointly define the inhalation channel 145. The inhalation channel 145 includes a first channel section 1451 and a second channel section 1452, a free end of the first channel section 1451 is in communication with the air passage 12, a free end of the second channel section 1452 is in communication with the inhalation inlet 141, and the second channel section 1452 and the inhalation inlet 141 are provided coaxially. Along the length direction of the shell 1, the central axis of the inhalation inlet 141 basically overlaps with the central axis of the shell 1, and because the second channel section 1452 and the inhalation inlet 141 are provided coaxially, a central axis of the second channel section 1452 also basically overlaps with the central axis of the shell 1. In this case, the second channel section 1452 may be located in a middle portion of an end of the shell 1 along the length direction. When the user inhales through the inhalation inlet 141, the vapor in the vaporization bin 13 may flow to a middle portion of the mouth of the user more smoothly through the air passage 12 and the inhalation channel 145, so that the vapor may be uniformly distributed in the mouth of the user.

Further, as shown in FIG. 30 and FIG. 35 , a mounting groove 1431 is formed in the body 143, at least one side of the mounting groove 1431 that is close to the air passage 12 is open, the inhalation shell 144 is arranged in the mounting groove 1431, and the inhalation shell 144 and an inner wall surface of the mounting groove 1431 jointly define the inhalation channel 145. The mounting groove 1431 is formed at an end of the body 143 along a length direction. The mounting groove 1431 may be formed by concaving of a part of an end surface of an end of the body 143 toward an other end of the body 143, a bottom wall of the mounting groove 1431 extends obliquely along a direction toward the air passage 12, and a side wall of the mounting groove 1431 has a communication interface in communication with the air passage 12, to implement communication between an end of the mounting groove 1431 and the air passage 12.

It should be noted that, the side of the mounting groove 1431 that is close to the air passage 12 may be completely open, that is, a side wall of the side of the mounting groove 1431 that is close to the air passage 12 is completely canceled. Alternatively, a side wall of the side of the mounting groove 1431 that is close to the air passage 12 may be partially reserved, that is, a height of the side wall of the open side of the mounting groove 1431 is lower than a height of another side wall of the mounting groove 1431, ensuring that in the length direction of the shell 1, the side wall of the side of the mounting groove 1431 that is close to the air passage 12 does not block the air passage 12. In this way, a structure of the shell 1 is simplified and is easy to process and make a mold.

Referring to FIG. 32 and FIG. 37 , a first groove 1441 concaving toward a direction away from a center of the shell 1 is formed in the inhalation shell 144, and the first groove 1441 and the mounting groove 1431 jointly define the inhalation channel 145. Therefore, an end of the first groove 1441 that faces the mounting groove 1431 may be tightly attached to the bottom wall of the mounting groove 1431. The first groove 1441 and the mounting groove 1431 can not only define a shape of the inhalation channel 145, but also can seal the inhalation channel 145, to guide flowing of the vapor and prevent the vapor from leaking to the outside from the inhalation channel 145.

In addition, that the first groove 1441 and the mounting groove 1431 jointly define the inhalation channel 145 is equivalent to dividing the inhalation channel 145 into two parts, one part of the inhalation channel 145 is formed in the inhalation shell 144 and the other part is formed in the shell 1, which helps reduce processing difficulty of the inhalation channel 145 and facilitates processing of the inhalation channel 145.

According to some specific embodiments of the present disclosure, as shown in FIG. 32 and FIG. 37 , the inhalation inlet 141 runs through a wall surface of the first groove 1441 that is away from the center of the shell 1.

It may be understood that, when the user inhales an e-cigarette, a part of the vaporization apparatus 100 that first extends into the mouth of the user is the wall surface of the first groove 1441 that is away from the center of the shell 1. According to such settings, the inhalation inlet 141 directly faces the mouth of the user. In this case, when a vapor output angle of the e-cigarette inclines, the vapor does not point to a side (for example, a left side, a right side, an upper side, or a lower side) of the mouth, feelings at positions in the mouth are approximately similar to each other, thereby further improving inhalation experience of the user.

According to some specific embodiments of the present disclosure, as shown in FIG. 29 and FIG. 30 , the first groove 1441 extends along the width direction of the shell 1, and an end of the first groove 1441 is in communication with the air passage 12. Therefore, the first groove 1441 may play a role of a transition connection between the air passage 12 and the inhalation inlet 141, so that the air passage 12 is in communication with the inhalation inlet 141, and smooth flowing of the vapor is ensured. In this case, the air passage 12 is located in the width direction of the shell 100 to reduce a thickness of the vaporization apparatus 100, and the inhalation inlet 141 is located at a middle position of the vaporization apparatus 100 in the width direction, so that the vapor flowing out of the inhalation inlet 141 directly faces and enters the mouth of the user, thereby improving inhalation experience of the user.

According to some specific embodiments of the present disclosure, as shown in FIG. 32 and FIG. 37 , an inner peripheral wall of the first groove 1441 includes a first peripheral wall section 1442, two second peripheral wall sections 1443, and a third peripheral wall section 1444. Specifically, the first peripheral wall section 1442 is connected to a side wall of the inhalation inlet 141 that is away from the air passage 12, one ends of the two second peripheral wall sections 1443 are respectively connected to two ends of the first peripheral wall section 1442 and both extend along a direction toward the air passage 12, and the third peripheral wall section 1444 is connected between the other ends of the two second peripheral wall sections 1443 and is located at a side of the central axis of the air passage 12 that is away from the inhalation inlet 141.

Therefore, the first peripheral wall section 1442 may surround a side of the inhalation inlet 141 that is away from the air passage 12. When assembly of the inhalation shell 144 and the shell 1 is completed, the first peripheral wall section 1442 can be attached to the bottom wall of the mounting groove 1431 to seal the side of the inhalation inlet 141 that is away from the air passage 12. Therefore, after the vapor flows to the first peripheral wall section 1442, the vapor may flow to the inhalation inlet 141 along the first peripheral wall section 1442, so that flowing of the vapor is guided while leakage of the vapor is prevented.

In addition, the first peripheral wall section 1442, the two second peripheral wall sections 1443, and the third peripheral wall section 1444 are connected end to end, and the first peripheral wall section 1442, the two second peripheral wall sections 1443, and the third peripheral wall section 1444 may perform entire sealing on a circumferential direction of the inhalation channel 145, thereby further improving entire sealing performance of the vaporization apparatus 100 and preventing vapor leakage.

In some specific embodiments of the present disclosure, as shown in FIG. 30 to FIG. 33 , a first engagement groove 146 is formed in one of the inhalation shell 144 and the bottom wall of the mounting groove 1431, a first engagement rib 14410 is arranged on the other of the inhalation shell 144 and the bottom wall of the mounting groove 1431, and the first engagement rib 14410 is engaged in the first engagement groove 146 and is arranged around the first groove.

For example, the first engagement rib 14410 may be arranged at a side of the inhalation shell 144 that faces the shell 1, and the first engagement groove 146 may be provided in the bottom wall of the mounting groove 1431. Through engagement between the first engagement rib 14410 and the first engagement groove 146, a connection strength between the inhalation shell 144 and the shell 1 may be improved, and the inhalation channel 145 may be sealed along a circumferential direction of the first groove, so that vapor leakage is prevented, and structure arrangement is more proper.

The inhalation shell 144 and the shell 1 are ultrasonically welded at the first engagement rib 14410.

By ultrasonically welding a joint between the first engagement rib 14410 and a groove wall of the first engagement groove 146, the connection strength between the shell 1 and the inhalation shell 144 may be relatively high, and welding quality at a welding position is higher, thereby implementing seamless welding. In this way, sealing performance between the shell 1 and the inhalation shell 144 may be improved, and an inner wall surface of the inhalation channel 145 may maintain flat, helping improve flowing smoothness of the vapor.

Optionally, referring to FIG. 30 and FIG. 33 , a second engagement groove 147 is formed in one of the inhalation shell 144 and the bottom wall of the mounting groove 1431, a second engagement rib 14411 is arranged on the other of the inhalation shell 144 and the bottom wall of the mounting groove 1431, and the second engagement rib 14411 is engaged in the second engagement groove 147. Through engagement between the second engagement rib 14411 and the second engagement groove 147, a connection strength between the inhalation shell 144 and the shell 1 may be improved, and sealing performance between the shell 1 and the inhalation shell 144 may be further improved, thereby preventing vapor leakage.

In some embodiments of the present disclosure, the second engagement rib 14411 may be in interference fit with the second engagement groove 147. In this way, connection stability between the second engagement groove 147 and the second engagement rib 14411 may be improved, so that connection between the shell 1 and the inhalation shell 144 is more reliable.

The inhalation shell 144 and the shell 1 are ultrasonically welded at the second engagement rib 14411. By ultrasonically welding a joint between the second engagement rib 14411 and a groove wall of the second engagement groove 147, the connection strength between the shell 1 and the inhalation shell 144 may be relatively high, and welding quality at a welding position is better, thereby implementing seamless welding. In this way, sealing performance between the shell 1 and the inhalation shell 144 is further improved, vapor leakage does not occur in the vaporization apparatus 100, and flowing of the vapor is more smooth.

As shown in FIG. 29 to FIG. 38 , an end of the shell 1 has a positioning protrusion 17, the positioning protrusion 17 is located at an other side of the shell 1 along the width direction, and a positioning groove 1449 engaged with the positioning protrusion 17 is formed in a shell bottom wall 1445. Through engagement and connection between the positioning protrusion 17 and the positioning groove 1449, relative displacement of the shell 1 and the inhalation shell 144 in the width direction of the shell 1 may be prevented, thereby further improving relative position stability between the inhalation shell 144 and the shell 1, and a mounting position of the inhalation shell 144 may be predetermined by using the positioning protrusion 17 and the positioning groove 1449, thereby reducing an assembly error, improving alignment accuracy, and reducing assembly difficulty between the inhalation shell 144 and the shell 1, so that assembly is more convenient.

Both the positioning protrusion 17 and the positioning groove 1449 may be arranged at an end away from the air passage 12, and the positioning protrusion 17 and the positioning groove 1449 do not cause interference with construction of the air passage 12 and the inhalation channel 145, so that flowing smoothness of the vapor can be ensured while the connection strength between the shell 1 and the inhalation shell 144 is improved, and structure arrangement is more proper.

In some specific embodiments of the present disclosure, as shown in FIG. 34 to FIG. 38 , at least one third engagement groove 148 is formed in one of the inhalation shell 144 and the bottom wall of the mounting groove 1431, at least one third engagement rib 14412 is arranged on the other of the inhalation shell 144 and the bottom wall of the mounting groove 1431, and the third engagement rib 14412 is in interference fit in the third engagement groove 148.

For example, the third engagement groove 148 and the third engagement rib 14412 may be arranged at a side of the vaporization apparatus 100 that is close to the air passage 12, and it may be learned from the above that the positioning groove 1449 and the positioning protrusion 17 may be arranged at a side of the vaporization apparatus 100 that is away from the air passage 12. In this way, engagement between the third engagement groove 148 and the third engagement rib 14412 may connect to and fix one sides of the inhalation shell 144 and the shell 1 that are close to the air passage 12, and engagement between the second engagement groove 147 in the positioning groove 1449 and the second engagement rib 14411 on the positioning protrusion 17 may connect to and fix the one sides of the inhalation shell 144 and the shell 1 that are away from the air passage 12. Therefore, the shell 1 are connected to the inhalation shell 144 at both two sides of the vaporization apparatus 100 along the width direction, so that connection reliability between the shell 1 and the inhalation shell 144 is further improved, and an entire connection strength of the vaporization apparatus 100 is higher.

As shown in FIG. 34 to FIG. 38 , at least one fourth engagement groove 149 is formed in one of the inhalation shell 144 and the bottom wall of the mounting groove 1431, at least one fourth engagement rib 14413 is arranged on the other of the inhalation shell 144 and the bottom wall of the mounting groove 1431, the fourth engagement rib 14413 is in interference fit in the fourth engagement groove 149, and the fourth engagement rib 14413 and the fourth engagement groove 149 are located at a side of the shell 1 along the width direction.

For example, the fourth engagement rib 14413 may be constructed on a side of the inhalation shell 144 that is close to the air passage 12 in a width direction of the inhalation shell 144, and the fourth engagement groove 149 may be constructed at a side of the shell 1 that is close to the air passage 12 in the width direction of the shell 1. In this way, through an interference fit between the fourth engagement rib 14413 and the fourth engagement groove 149, the connection strength between the inhalation shell 144 and the shell 1 on a side close to the air passage 12 in the width direction of the vaporization apparatus 100 may be further improved, and an entire connection strength of the vaporization apparatus 100 may also be improved correspondingly.

According to some embodiments of the present disclosure, as shown in FIG. 40 , the inhalation shell 144 may be sleeved on the shell 1.

Specifically, referring to FIG. 41 and FIG. 42 , the inhalation shell 144 includes a shell bottom wall 1445 and a shell peripheral wall 1446. The inhalation inlet 141 is formed in the shell bottom wall 1445, the shell bottom wall 1445 is opposite to an end of the shell 1 along the length direction, the inhalation channel 145 is formed or located between the shell bottom wall 1445 and an end of the shell 1, and the shell peripheral wall 1446 is connected to an outer peripheral side of the shell bottom wall 1445 and covers an outer peripheral surface of the shell 1.

In this way, the inhalation channel 145 defined by the shell bottom wall 1445 and the shell 1 may guide flowing of the vapor, and a contact area between the shell peripheral wall 1446 and the shell 1 may be relatively great, which facilitates connection and fixing between the inhalation shell 144 and the shell 1, and helps improve the connection strength between the inhalation shell 144 and the shell 1. Therefore, a structural strength of the vaporization apparatus 100 becomes higher, sealing performance between the inhalation shell 144 and the shell 1 may also be improved, thereby preventing the vapor from leaking from a joint between the shell 1 and the inhalation shell 144, and improving utilization of the e-liquid in the vaporization apparatus 100.

As shown in FIG. 40 , a second groove 1432 concaving toward a direction away from the shell bottom wall 1445 is formed at an end of the shell 1, the second groove 1432 is in communication with the air passage 12, a surrounding portion 16 surrounding the air passage 12 and the second groove 1432 is formed at the end of the shell 1, a third groove 1447 concaving toward a direction away from the shell 1 is formed in the shell bottom wall 1445, the third groove 1447 is in communication with the inhalation inlet 141, a protrusion 1448 surrounding the inhalation inlet 141 and at least a part of the third groove 1447 is arranged on the shell bottom wall 1445, and the protrusion 1448 and the surrounding portion 16 abut against each other and jointly define the inhalation channel 145.

Based on this, positions of the second groove 1432 and the third groove 1447 in the width direction and the thickness direction of the vaporization apparatus 100 correspond to each other, and the second groove 1432 and the third groove 1447 form the inhalation channel 145, thereby ensuring flowing of the vapor between the air passage 12 and the inhalation inlet 141. In addition, an end of the protrusion 1448 that faces the surrounding portion 16 may be tightly attached to an end of the surrounding portion 16 that faces the protrusion 1448. In this way, the protrusion 1448 and the surrounding portion 16 can define a shape of the inhalation channel 145, and can also seal the inhalation channel 145, to guide flowing of the vapor, thereby preventing the vapor from leaking to the outside from the inhalation channel 145.

In addition, that the protrusion 1448 and the surrounding portion 16 abut against each other and jointly define the inhalation channel 145 is equivalent to dividing a side wall of the inhalation channel 145 into two parts, where one part of the inhalation channel 145 is formed in the protrusion 1448 and the other part is formed in the surrounding portion 16. This helps reduce process difficulty of the inhalation channel 145 and facilitates processing of the inhalation channel 145. Besides, the inhalation channel 145 is formed by the second groove 1432 and the third groove 1447, so that a cross-sectional area of the inhalation channel 145 is greater, vapor flowing is more smooth, and an amount of outputted vapor is greater.

As shown in FIG. 33 to FIG. 35 , the surrounding portion 16 includes a first surrounding section 161 and a second surrounding section 162 that are connected at both ends. The first surrounding section 161 is arranged around an outer peripheral side of the third groove 1447, the second surrounding section 162 is arranged around an outer peripheral side of the air passage 12, and a side surface of the second surrounding section 162 that is close to the shell bottom wall 1445 is lower than a side surface of the first surrounding section 161 that is close to the shell bottom wall 1445.

In this way, the first surrounding section 161 and the second surrounding section 162 has a height difference in the length direction of the shell 1, so that the surrounding portion 16 can be attached to the protrusion 1448 in the length direction of the vaporization apparatus 100 and can be attached to the protrusion 1448 in the width direction of the vaporization apparatus 100, and an attach area between the surrounding portion 16 and the protrusion 1448 is greater. In addition, in the width direction of the shell 1, the surrounding portion 16 may abut against the protrusion 1448 due to the height difference between the first surrounding section 161 and the second surrounding section 162, to limit the inhalation shell 144 and the shell 1. Therefore, no relative displacement is generated between the inhalation shell 144 and the shell 1 in the width direction of the vaporization apparatus 100, and connection is more reliable.

A cross-sectional area of the air passage 12 gradually increases along a direction toward the inhalation inlet 141. In this case, a cross-sectional area of an end of the air passage 12 that is close to the vaporization bin 13 is smallest, and a cross-sectional area of an end of the air passage 12 that is away from the vaporization bin 13 is greatest. With such arrangement, during inhalation by the user, it may be ensured that the user can inhale a sufficient amount of vapor, thereby ensuring user experience.

According to some embodiments of the present disclosure, a central axis of the air inlet 71 deviates from the central axis of the air passage 12. As shown in FIG. 1 , the air inlet 71 is located at a middle portion of the base 72, and along a width direction of the body 143, the central axis of the air inlet 71 basically overlaps with a central axis of the body 143. With such arrangement, it may be ensured that air flowing to the vaporization bin 13 through the air inlet 71 can flow to each position of the vaporization bin 13, so that the air is uniformly distributed in the vaporization bin 13, and it may be ensured that the air can be fully mixed with the vaporized medium.

As shown in FIG. 23 , an air inlet channel 7211 may be provided in the base bottom wall 721, the air inlet channel 7211 includes an air inlet hole and an air outlet hole, the air outlet hole forms the air inlet 71, and the air outlet hole offsets toward a side that is away from the air passage 12 relative to the air inlet hole. Specifically, in the width direction, the air outlet hole offsets toward the side that is away from the air passage 12 relative to the air inlet hole. In this case, the air passage 12 and the air outlet hole are respectively located on two ends of the air inlet hole along a radial direction. During operation of the vaporization apparatus 100, external air flows to the vaporization bin 13 through the air inlet hole and the air outlet hole, and flows to the mouth of the user through the air passage 12 and the inhalation inlet 141 after being mixed with the vaporized medium in the vaporization bin 13. Therefore, a flowing path of the air in the vaporization bin 13 may be increased, and the air can be fully mixed with the vaporized medium.

According to some embodiments of the present disclosure, the vaporization apparatus 100 applied to an e-cigarette further includes an air-permeable and e-liquid-resistant member 10, and the air-permeable and e-liquid-resistant member 10 covers the air outlet hole.

According to some embodiments of the present disclosure, the air-permeable and e-liquid-resistant member 10 is fixed to an end surface of an end of the air inlet channel 7211 that is located at the air outlet hole.

According to some embodiments of the present disclosure, the air-permeable and e-liquid-resistant member 10 is fixed by bonding to an end surface of an end of the air inlet channel 7211 that is located at the air outlet hole.

According to some embodiments of the present disclosure, referring to FIG. 23 and FIG. 24 , the vaporization core seal member 9 is arranged between the vaporization core 3 and the vaporization core fixing structure 4, the vaporization core 3 may be in interference fit with the vaporization core fixing structure 4 through the vaporization core seal member 9, thereby ensuring sealing performance between the vaporization core 3 and the vaporization core fixing structure 4, and preventing the to-be-vaporized medium from leaking to the vaporization bin 13 through a gap between the vaporization core 3 and the vaporization core fixing structure 4. The baffle 46 is arranged at a side of the vaporization core seal member 9 that is close to the air passage 12. In this way, the baffle 46 may block the mixed airflow flowing from the vaporization bin 13 to the air passage 12, to reduce a flow rate of the mixed airflow, so that the vaporized medium and the air in the mixed airflow are fully mixed. Optionally, the baffle 46 and the vaporization core seal member 9 may be an integrally formed structural member.

The inhalation inlet 141 may be a strip-shaped hole extending along the width direction of the shell 1. For example, the inhalation inlet 141 may be an elliptical hole, an oblong hole, or a rectangular hole. Therefore, the inhalation inlet 141 has a simple structure and is easy to process.

A cross section of the air passage 12 may be in a shape of a circle, but is not limited thereto. The cross section of the air passage 12 may alternatively in a shape of a rectangle, an ellipse, or an oblong.

The body 143 and the base 72 may be made of an elastic semi-transparent material or an elastic transparent material. By arranging the shell 1 separately, processing of the body 143 and the base 72 is facilitated, and processing difficulty of the shell 1 can be reduced, so that production costs of the shell 1 is reduced, and a production speed of the shell 1 is improved. In addition, this arrangement helps improve processing precision of structures of the vaporization bin 13, the liquid storage bin 11, and the air passage 12 that are located in the shell 1.

A specific operation process of the vaporization apparatus 100 according to an embodiment of the present disclosure is as follows:

After the vaporization apparatus 100 is combined with a cigarette rod, when a user inhales at the inhalation inlet 141, a pneumatic sensor in the cigarette rod is triggered and sends a signal to drive the vaporization core 3 to perform heating, a to-be-vaporized such as e-liquid in the liquid storage bin 11 is heated and vaporized in the vaporization surface of the vaporization core 3 and then outputted to the vaporization bin 13 through the vaporization surface. In addition, external air enters the vaporization bin 13 through the air inlet channel 7211, the air entering the vaporization bin 13 enters the vaporization bin 13 after being diverted by the first air guide metal plate 74, and the baffle 46 can reduce flow rates of a vaporized medium and the air, so that the vaporized medium and the air in the vaporization bin 13 can be fully mixed. A mixed vapor flows to the air passage 12 through the vaporization bin exit 2, and the vapor in the air passage 12 flows to the mouth of the user through the inhalation channel 145 and the inhalation inlet 141. With generation of the vaporized medium, the to-be-vaporized medium in the liquid storage bin 11 is gradually absorbed to the vaporization surface, an air pressure in the liquid storage bin 11 decreases and forms a negative pressure, and an air pressure in the vaporization bin 13 is relatively high. In this case, the airflow in the vaporization bin 13 may flow to the vent groove 44 through the vent cavity 42 and the vent hole 43, and the airflow in the vent groove 44 may push the vent elastic portion 511 to generate deformation to open the vent channel 6, thereby implementing an air pressure balance between the liquid storage bin 11 and the vaporization bin 13. When the air pressure of the vaporization bin 13 and the air pressure of the liquid storage bin are balanced, the vent elastic portion 511 restores to an original state and blocks an end of the vent groove 44 that is close to the liquid storage bin 11, to prevent leakage of the to-be-vaporized medium in the liquid storage bin 11.

According to a second aspect of the present disclosure, an embodiment provides an e-cigarette (not shown in the figure), including the vaporization apparatus 100 applied to an e-cigarette provided in the embodiment according to the first aspect of the present disclosure.

According to the e-cigarette provided in this embodiment of the present disclosure, by using the foregoing vaporization apparatus 100, the e-liquid in the vaporization bin 13 can quickly flow to the air passage 12, thereby reducing resistance during inhalation by a user and improving user experience.
